View SpecificationsThe Paradigm Shift in Advanced Packaging: Glass Core Substrates & TGV
As the semiconductor industry races toward 2nm process nodes and heterogeneous chiplet integration, conventional organic core substrates (such as ABF) face physical boundaries in thermal dissipation, warping, and interconnect density. Inorganic glass wafers, high-purity quartz substrates, and synthetic fused silica (JGS1) are setting new benchmarks for high-frequency computing and photonic co-packaging.
Next-Gen Glass Core Packaging (TGV)
Silicon and organic substrates are challenged by significant parasitic capacitance and mechanical deformation at multi-die packaging scales. Through-Glass Via (TGV) technology, enabled by our ultra-flat Borofloat 33 and synthetic quartz substrates, provides exceptional electrical isolation, near-zero dielectric loss at RF/millimeter-wave frequencies, and superior dimensional stability under thermal cycling.
Co-Packaged Optics & Silicon Photonics
Optical interconnects within AI server clusters demand precision optical coupling. BY Photonics fabricates JGS1 UV-grade fused silica plates, micro-grooved quartz arrays, and optical carrier wafers that support sub-micron fiber-to-chip alignment. Low absorption from 193 nm to 2500 nm ensures ultra-low insertion loss in high-throughput data transceivers.
Wide Bandgap & MEMS Anodic Bonding
Micro-Electro-Mechanical Systems (MEMS) sensors and GaN/SiC power semiconductors require thermal coefficient matching during high-temperature anodic bonding. Our engineered Borofloat 33 wafers closely track the thermal expansion curve of pure silicon (CTE: 3.25 × 10⁻⁶/K), preventing internal shear stress, micro-cracks, and seal degradation during vacuum packaging.
| Substrate Material Class | Transmission Bandwidth | Thermal Expansion (CTE) | Dielectric Constant (1 MHz) | Maximum Service Temp. | Primary Industrial Sector |
|---|---|---|---|---|---|
| JGS1 Synthetic Fused Silica | 185 nm – 2,500 nm (DUV/UV) | 0.54 × 10⁻⁶ / K | 3.75 | 1,100 °C | EUV/DUV Lithography, CPO, Laser Windows |
| JGS2 Optical Fused Quartz | 220 nm – 2,500 nm (VIS/NIR) | 0.55 × 10⁻⁶ / K | 3.80 | 1,150 °C | Semiconductor Furnace Ware, Sight Glasses |
| Borofloat 33® Borosilicate | 350 nm – 2,500 nm | 3.25 × 10⁻⁶ / K (Si-Matched) | 4.60 | 450 °C (Short 500 °C) | MEMS Anodic Bonding, Biochips, Sensors |
| Optical Single-Crystal Sapphire | 170 nm – 5,500 nm (UV to MWIR) | 5.8 × 10⁻⁶ / K (C-axis) | 9.3 – 11.5 | 1,800 °C | High-Pressure Viewports, SOS Wafers, Aero Sensors |
| Spectralon-Grade PTFE Matrix | 250 nm – 2,500 nm (Diffuse Reflect.) | N/A (Polymer Complex) | 2.10 | 260 °C | Diode-Pumped Laser Cavities, Integrating Spheres |
Global Enterprise Sourcing Architecture: Mitigating Yield Loss
In Tier-1 semiconductor processing and medical laser manufacturing, component failure carries exponential downstream costs. International engineering teams rely on stringent metrology verifications to avoid wafer breakage, chuck de-chucking errors, and optical degradation during plasma etching.
Subsurface Damage (SSD)
Micro-cracks beneath mechanically ground wafers propagate during thermal cycling, leading to catastrophic wafer failure inside lithography or PECVD tools. BY Photonics implements multi-stage Chemical Mechanical Planarization (CMP) and proprietary acid leaching to completely eliminate SSD.
TTV, Bow & Warp Limits
For automated electrostatic or vacuum chucks, wafer planarity is non-negotiable. Our double-sided planetary lapping maintains Total Thickness Variation (TTV) under 1.0 µm and Bow/Warp under 10 µm across standard 4", 6", 8", and 12" diameter wafer formats.
Edge Profile & Notching
Edge chipping is the #1 initiator of slip-line defects in thermal furnaces. All wafers are processed with SEMI standard T-shape or rounded C-shape edge grinding, complemented by standard SEMI orienting flats or precision-cut laser alignment notches.
Class 100 Cleanroom Packaging
Substrates are ultrasonically cleaned using multi-frequency deionized water megasonic scrubbers, verified for particle counts (0.1 µm thresholds), and vacuum-sealed in single-wafer cassettes or multi-slot coin-pack carriers under Class 100 laminar clean benches.
Full SEMI & ISO Traceability Certification
Every shipment from our Tianjin production facility includes comprehensive lot inspection sheets, laser interferometry maps (Zygo), and raw material melt boule certificates. We empower procurement teams with complete supply chain transparency from raw SiO₂ crystal synthesis to final vacuum packaging.
Vertically Integrated Manufacturing: Cost Agility & Defect Zero
Operating from our 3,000+ m² standardized production facility in Tianjin, China, BY Photonics bridges the gap between precision optical cold working and high-temperature flame fusion under one single roof.
Unified Cold & Hot Processing
Subcontracting glass processing across fragmented vendors creates cumulative tolerance drift and micro-cracking. BY Photonics integrates wire sawing, multi-spindle CNC abrasive machining, double-sided planetary lapping, chemical-mechanical polishing (CMP), and oxyhydrogen flame working in a seamless chain of custody.
Supply Chain Resilience & Raw Material Security
By securing direct partnerships with domestic and global raw material synthesizers of JGS1, JGS2, JGS3, Corning, and Schott ingot stocks, we buffer international customers against supply shocks. Even during global supply crunches, our standing raw block reserves ensure reliable delivery timelines.
Direct-to-Engineer Rapid Prototyping
Traditional suppliers route CAD models through non-technical sales agents, leading to days of miscommunicated DFM reviews. At BY Photonics, your STEP, DXF, or PDF engineering drawings are assessed within 24 working hours by a senior process engineer who validates bevel angles, edge finishes, and tolerance budgets.
High-Performance Substrates in Field Deployments
Across cleanroom fabs, laser treatment clinics, and defense test beds, our precision glass wafers and custom quartz components deliver uncompromising structural and optical fidelity.
Semiconductor Gas Distribution & Plasma Etch
Our custom optical quartz gas distribution plates withstand aggressive chlorine, fluorine, and oxygen RF plasma atmospheres inside reactive-ion etch (RIE) and PECVD reactor chambers. High material purity prevents metal ion contamination and particulate flaking on 300 mm silicon wafers.
High-Duty Diode-Pumped Laser Cavities
Ceramic laser reflectors and diffuse high-reflectivity PTFE chambers provide diffuse, uniform light distribution for Nd:YAG, Alexandrite, and diode-pumped solid-state lasers. Chemically inert, UV-stable materials prevent laser power degradation and cavity scorching under continuous multi-kilowatt pumping.
Fiber Optic Couplers & Waveguide Arrays
Our precision square groove quartz substrates enable tight fiber-core alignment for multi-channel telecommunication splitters, dense wavelength division multiplexing (DWDM) modules, and high-density fiber arrays. Polished micro-groove tolerances ensure sub-micron core concentricity.
Medical Laser Windows & Cryo Distance Gauges
Durable slider windows with specialized dual-band anti-reflective (AR) coatings at 755 nm (Alexandrite) and 1064 nm (Nd:YAG) protect internal optical trains in aesthetic and surgical laser heads. Engineered to withstand cryogen spray bursts, thermal shocks, and high-repetition beam pulses.
